Grand Theft Auto IV: The Lost and Damned Walkthrough & Strategy Guide

Once you have the truck, it's time to head to your destination, which is on the Algonquin side of the Booth Tunnel. You'll see a cutscene of the guy you have to fake-spring from police custody being escorted from a nearby jail. So, begin driving to your destination on the far side of Booth Tunnel, following the route laid out for you by the GPS. Once you arrive in the tunnel, you'll realize that you need to be on the other side of the tunnel (as if you were heading with traffic back into Alderney). Follow the on-screen prompt and park your car along the two lanes there, fitting it into the arrows as shown on-screen.

Once you do that, the cops will show up in their prisoner caravan. Since your truck is blocking the road, they immediately know something's up and come out with guns drawn. You'll begin behind your truck, well-covered, so begin firing when you feel comfortable, taking out the cop in front of you and a few other stragglers before switching to your RPG. Be absolutely certain you don't target the prisoner truck, but detonate everything else, especially the cop cars. This will kill several cops and effectively eliminate their cover. Once all enemies are eliminated (the cops will show up as red dots on your HUD), jump in the prisoner truck. It's time to make our escape.
